Altair HyperMesh
New Features
- New LS-DYNA Solver Profile R13.1
Enhancements
- Keyword Migration to New Entity
- *CONSTRAINED_JOINT_STIFFNESS_(OPTIONS) keywords are migrated from the Property entity to the Constraint entity.
- New Supported Keywords
- Constrained: *CONSTRAINED_JOINT_STIFFNESS_CYLINDRICAL
- Keywords Updates Till R13.1 Version
- Airbags: New attributes added in *DEFINE_CPM_VENT.
- LS-DYNA I10 Format
- Support of long=s in *KEYWORD along with i10=y. Long=s can be added via the solver deck export options when i10 format is activated.
- Performances
- Relevant performance improvements made in the Model Checker.
Resolved Issues
- A correction has been made in the Position/Transformation tool when Positions are applied or un-applied. Only selected Position is now affected and performances are improved.
- Card4 in *MAT_SEATBELT_2D is now treated as optional.
- Export issue of *CONTROL_MPP_DECOMPOSITION_TRANSFORMATION has been fixed.
- Multiple corrections have been made in reading and editing *MAT_3-PARAMETER_BARLAT_(OPTIONS). Anisotropy axis definition attributes are read and maintained on export independently from the AOPT value.
- A correction in reading *MAT_ORTHOTROPIC_ELASTIC has been made. Anisotropy axis definition attributes are read and maintained on export independently from the AOPT value.
- A correction in reading *MAT_LAMINATED_COMPOSITE_FABRIC has been made. AOPT value wasn't read properly.
- A correction in reading *SENSOR_SWITCH_CALC-LOGIC has been made.
- *ELEMENT_SPH attributes are now fully exposed in the Entity Editor.
- Show/Hide/Isolate/Review operations are now working on Position entity when defined on *INCLUDE_TRANSFORM.
Altair HyperView
New Features
- Support of “% thickness” results from d3plot femzip file.
- Support of Heat Flux results from d3plot file.
- Support of temperature results from d3plot file depending on the MSSCL attribute value defined in *DATABASE_EXTENT_BINARY.
- Material history variables are now shown as “Var1”, Var2, Var3,…" since those variables are dependent from the material models.
- Support of history variables from d3plot file for *CONSTRAINED_INTERPOLATION_SPOTWELD.
Altair HyperGraph
Resolved Issues
- Displaying data from LS-DYNA time history files.
- Crash due to an indexing issue with LS-DYNA time history files in report templates.
